Chemical composition (%) DIN EN 12167
CuZn41Pb1Al This alloys is used for production of profiles by hot extrusion. Aluminium imparts a golden lustre, avoiding need for further polishing. The alloys with more than 1.6% Pb have very good machinability. s. It is a very good alloy for use in profiles which provide complex shapes or very thin walls, Handrails, Decorative Profiles, Standard Angles, Standard T sections, Standard Channels, Trim & Flooring Profiles and Ironmongery Profies.
Due to the alloying of Al CuZn43Pb1Al has a golden yellow colour. Common name is Architectural “Bronze” also know as Architectural Brass
Generally supplied as extruded / as manufactured.
